* Fix values in __mpexp_twomm1Siddhesh Poyarekar2013-01-021-8/+8
|
* Split mantissa calculation loop and add branch predictionSiddhesh Poyarekar2013-01-021-24/+43
|
* Add assert for potential access beyond array bounds in m1npSiddhesh Poyarekar2013-01-021-4/+17
| | | | | | | | | | | The mpexp code has an access into m1np: for (i=n-1; i>0; i--,n--) { if (m1np[i][p]+m2>0) break; } which could break for p >= 18 or i >= 7. Fortunately this code is never called due to the way the exp function is implemented since values having exponent less than -55 return 1.0. Make sure that if it gets called in future, it is trapped.
